PyCon CZ - Day 3

The third day of the con­fe­ren­ce was hos­ted on a di­ffe­rent ve­nue, the Cze­ch ­Te­ch­ni­cal Uni­ver­si­ty of Pra­gue.

The workshops

I sig­ned up for two wo­rks­hop­s: sear­ch for fun (and pro­fi­t), an­d Effec­ti­ve­ly run­ning py­thon appli­ca­tions in Ku­ber­ne­tes / OpenS­hi­ft.

They we­re bo­th grea­t, and le­ft me wi­th lo­ts of in­te­res­ting to­pi­cs for re­sear­ch and do fur­ther wo­rk.

The first one walked through the workings of elasticsearch-dsl-py, which was great not only because the explanations were superb, but also because there is probably no better way to review this than from the author himself. I was already experienced with the library, since I’ve used, Elasticsearch with Python, but even though, this workshop gave me a deeper understanding of the concepts behind it (there was a lot about the internals of Elasticsearch, how it works, its configuration, concepts of information retrieval, etc.), so I got new ideas. On the practical side, I’ll check this project.

The second one started with an overview of Kubernetes and OpenShift, and shortly thereafter, we started with the practical assignment, on which we deployed an application on the OpenShift cloud.

The tools required for this are quite interesting. Personally, I prefer the command line tool (oc client) to the web interface, not only because it seems more familiar (for one using Linux), but also because it provides more features and a richer interface. For example (at this point), cron jobs cannot be created through the web interface, but only from the command line with this client (and it was part of the exercise). I personally always find the command line much more complete, useful, and rich (for example it allows automation, scripting, etc.), compared to UIs, so I’ll use the client.

The Venue

The uni­ver­si­ty has a rea­lly ni­ce buil­din­g, pla­ced in an equa­ll­y-­ni­ce stu­den­t a­rea.
